Simplify 2m2×(2m3)

  • Last Updated : 12 Oct, 2021

Mathematics is not only about numbers but it is about dealing with different calculations involving numbers and variables. This is what basically known as Algebra. Algebra is defined as the representation of calculations involving mathematical expressions that consist of numbers, operators, and variables. Numbers can be from 0 to 9, operators are the mathematical operators like +, -, ×, ÷, exponents, etc, variables like x, y, z, etc.

Exponents and Powers

Exponents and powers are the basic operators used in mathematical calculations, exponents are used to simplifying the complex calculations involving multiple self multiplications, self multiplications are basically numbers multiplied by themselves. For example, 7 × 7 × 7 × 7 × 7, can be simply written as 75. Here, 7 is the base value and 5 is the exponent and the value is 16807. 11 × 11 × 11, can be written as 113, here, 11 is the base value and 3 is the exponent or power of 11. The value of 113 is 1331.

Exponent is defined as the power given to a number, the number of times it is multiplied by itself. If an expression is written as cxy where c is a constant, c will be the coefficient, x is the base and y is the exponent. If a number say p, is multiplied n times, n will be the exponent of p. It will be written as

p × p × p × p … n times = pn

Basic rules of Exponents

There are certain basic rules defined for exponents in order to solve the exponential expressions along with the other mathematical operations, for example, if there are the product of two exponents, it can be simplified to make the calculation easier and is known as product rule, let’s look at some of the basic rules of exponents,

  • Product Rule ⇢ an × am = an + m
  • Quotient Rule ⇢ an / am = an – m
  • Power Rule ⇢ (an)m = an × m or m√an = an/m
  • Negative Exponent Rule ⇢ a-m = 1/am
  • Zero Rule ⇢ a0 = 1
  • One Rule ⇢ a1 = a

 What is 2m2(2m3)?

Solution:

As it is clearly seen, the entire problem statement is asking for a simplification using exponent rules, looking at the expression 2m2(2m3), it is observed that the product rule of exponents can be easily applied to this expression,

Step 1: Remove the parenthesis and write terms with their exponents.

2m2(2m3) = 2m2 × 2m3

Step 2: Apply the Product rule of exponents.

Product Rule ⇢ an × am = an + m

2m2 × 2m3 = 2m(2 + 3)

Therefore, 2m5 is the value obtained.

Question 1: What is 9m5(8m7)?

Solution:

As it is clearly seen, the entire problem statement is asking for a simplification using exponent rules, looking at the expression 9m5(8m7), it is observed that the product rule of exponents can be easily applied to this expression,

Step 1: Remove the parenthesis and write terms with their exponents.

9m5(8m7) = 9m5 × 8m7

Step 2: Apply the product rule of exponents.

Product Rule ⇢ an × am = an + m

9m5 × 8m7 = 9 × 8m(5 + 7)

Therefore, 72m12 is the value obtained.

Question 2: Simplify (x7)(x2)

Solution:

As it is clearly seen, the entire problem statement is asking for a simplification using exponent rules, looking at the expression (x7)(x2), it is observed that the product rule of exponents can be easily applied to this expression,

Product Rule ⇢ an × am = an + m

x7 × x2 = x(7 + 2)

= x9

Therefore, x40 is the value obtained.

Question 2: Simplify 50(x0)(x9)

Solution:

As it is clearly seen, the entire problem statement is asking for a simplification using exponent rules, looking at the expression 50(x0)(x9), it is observed that the product rule of exponents can be easily applied to this expression,

Product Rule ⇢ an × am = an + m

50[x0 × x9] = 50x(0 + 9)

= 50x9

Therefore, 50x9 is the value obtained.
