Question

1. Write the products in the exponential form :

(i) (x . x . x . x . x) (x . x)

(ii) -1(n.n.n) (n.n)

(iii) y⁸ × y⁵× y²
​

Answer 1

Step-by-step explanation:

Summary: Whole numbers can be expressed in standard form, in factor form and in exponential form. Exponential notation makes it easier to write a number as a factor repeatedly. A number written in exponential form is a base raised to an exponent. The exponent tells us how many times the base is used as a factor.

Answer 2

Answer:-

Question 1.

$\sf (x.x.x.x.x)(x.x)$

$\sf = {x}^{5} \times {x}^{2}$

$\sf = {x}^{5 + 2}$

$\sf = {x}^{7}$

Question 2.

$\sf - 1(n.n.n)(n.n)$

$\sf = - 1 \times {n}^{3} \times {n}^{2}$

$\sf = - {n}^{5}$

Question 3.

$\sf {y}^{8} . {y}^{5} . {y}^{2}$

$\sf = {y}^{8 + 5 + 2}$

$\sf = {y}^{15}$
