Question

1) Express in exponent form with base 2 :-128
do as directed .​

Answer 1

Step by step explanation :-

Given :-

To express 128 in exponential form

Concept to know :-

First of all what is exponential form

Exponential form is nothing but we have to write the number in terms of bases and powers .For example as they said to write the exponential form of 128 we can write exponential form by using prime factorisation

Solution :-

$\begin{array}{c|c} \sf 2 & \sf 128 \\ \sf 2 & \sf 64 \\ \sf 2 & \sf 32 \\ \sf 2 & \sf 16 \\ \sf 2 & \sf 8 \\ \sf 2 & \sf 4 \\ \sf 2 & \sf 2 \\ \sf 2 & \sf 1 \end{array}$

So, from above 128 can be written as 2× 2 ×2 ×2 ×2 ×2 ×2

128 = 2⁷

Hence the exponential form of 128 is 2⁷ . Its base also 2

In 2⁷

$\left \{ {{2\: is\: base } \atop {7 \: is \: power}} \right.$

Here If you observe 128 is in exponential form because It has power and base
