Question

Give the standard form of:
(i) 0.000000942

Answer 1

Answer:

0.000000942 in standard form is $9.42 *10^{-7}$

Step-by-step explanation:

Given

0.000000942

To convert the number into standard form, we have to write it as the power of 10

Here,

$0.000000942 =\frac{9.42}{10000000} \\\\= 9.42 *10^{-7}$

So 0.000000942 in standard form is $9.42 *10^{-7}$

Answer 2

Answer:

the answer to this question is

$9.42 \times {10}^{ - 7}$

step-by-step explanation:

Here the number is 0.000000942

now

$\frac{942}{1000000000} \\ = \frac{9.42}{10000000} \\ = \frac{9.42}{ {10}^{7} } \\ = 9.42 \times {10}^{ - 7}$

because we know that,

${a}^{n} = \frac{1}{a {}^{ - n} }$
