# How do you write the expression 7*7 using exponents?

Jan 4, 2017

${7}^{2}$

#### Explanation:

Using exponents is a ' shorthand' method for expressing $\textcolor{b l u e}{\text{repeated multiplication}} .$ That is the same value being multiplied by itself many times. The value of the exponent is the number of times the value is being multiplied by itself.

$\Rightarrow 7 \times 7 = {7}^{2} \text{ since there are 2 sevens being multiplied}$

$7 \times 7 \times 7 = {7}^{3} \text{ since 3 sevens being multiplied}$

${7}^{4} \text{ represents } 7 \times 7 \times 7 \times 7$

$\text{and so on}$
