Question

exponential form of -8/27​

Answer 1

Answer:

(-2/3)^3......is your answer

Answer 2

The exponential form = $({ \frac{ - 2}{3} })^{3}$

GIVEN:- -8/27

TO FIND:- exponential form

SOLUTION:-

• If we multiply a number by itself several times, then it can be written in a short form called exponential or power notation.

• In general, for any rational number a and a positive integer n we define ${a}^{n}$ = a×a×a (n times). The number 'a' is called the base and n is called the exponent or power or index.

According to the question,

-8/27 can be written as,

(-2)³ = -8

(3)³= 27

$\frac{ - 8}{27} \\ = \frac{ - 2 \times - 2 \times - 2}{3 \times 3 \times 3 } \\ = \frac{ { - 2}^{3} }{ {3}^{3} } \\ = ({ \frac{ - 2}{3} })^{3}$

Hence, the exponential form= $( { \frac{ - 2}{3} })^{3}$
