Question

Write the following expression using exponents -3x7x7x7x7x7x7

Answer 1

Solution -:

$\bold{ \underline{ \underline{Given}}}$

-3x7x7x7x7x7x7

$\bold{\underline {\underline{lets \: begin}}}$

We have,,

$-3 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \\ = - 3¹ \times {7}^{6}$

• exponent and shortcut to express a multiplication of number by itself several times explain us how many time we should multiply the number by itself this process of using exponent is called raising to a power where the exponent is the power.

Law of exponent -:

• a ⁰ = 1
• a ^ m × a ^ n
• (a^m)^n
• a^m × b^ m

As like example→ 2⁴

here 2 is base and 4 is power , index or exponent. and 2⁴ is known as Exponential form.
