Question

What is the value of R

Answer 1

Answer:

2.45 × $10^{6}$

Step-by-step explanation:

using the rules of exponents

• $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$

• $(a^m)^{n}$ = $a^{mn}$

evaluating the numerator

(3.8 × $10^{5}$)² = 3.8² × $(10^5)^{2}$ = 14.44 × $10^{10}$

R = $\frac{14.44.10^{10} }{5.9.10^{4} }$

  = $\frac{14.44}{5.9}$ × $\frac{10^{10} }{10^{4} }$

  = 2.45 × $10^{6}$ ← to 2 dec. places
