Question

hey guys please solve this​

Answer 1

Step-by-step explanation:

$= \frac{1.7 \times {10}^{ - 8} \times {10}^{3} }{3.14 \times ({0.25 \times {10}^{ - 3} })^{2} } \\ = \frac{1.7 \times {10}^{ - 5} }{3.14 \times ({0.25})^{2} \times {10}^{ - 6} } \\ = \frac{1.7 \times {10}^{ - 5} \times {10}^{ 6} }{3.14 \times {0.25}^{2} } \\ = \frac{1.7 \times 10}{3.14 \times {0.25}^{2} } \\ = \frac{17}{3.14 \times 0.0625} \\ = \frac{17}{0.19625} \\ = 86.6$
