Question

Question 2(iv)
Express the following in exponential form:
(iv) $5\times 5\times 7\times 7\times 7$

Answer 1

Number written in the form of base and exponent is called the exponential form.

(iv) $5\times 5\times 7\times 7\times 7$

In the given form, 5 occurs twice and 7 occurs thrice.

$\therefore$ The exponential form is $5^2\times 7^3$

Here 5, 7 are bases and 2, 3 are exponents.
