Question

6. Write in usual form:
(a) 8.03 x (10)-⁷
(b) 1.426 × (10)-⁵​

Answer 1

Answer:

(a) 0.000000803 (b) 0.00001426

Step-by-step explanation:

From the question,

(a)

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8.03 \times {10}^{ - 7} \\ = \frac{8.03}{ {10}^{7} } \\ \: \: \: \: \: \: \: \: \: \: \: = \frac{8.03}{10000000} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 0.000000803$

(b)

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 1.426 \times {10}^{ - 5} \\ = \frac{1.426}{ {10}^{5} } \\ \: \: \: \: = \frac{1.426}{100000} \\ \: \: \: \: \: \: \: \: \: \: \: = 0.00001426$

Hence, the answer is (a) 0.000000803 and (b) 0.00001426
