Answer
(a) $ 1.8 \times 10^{-2}$
(b) $1.14 \times 10^{10}$
(c) $ -5 \times 10^4$
(d) $ 1.3 \times 10^3$
Work Step by Step
(a) $0.0095 + 0.0085 = 0.018 = 1.8 \times 10^{-2}$
(b)
$653/(5.75 \times 10^{-8}) = \frac{653}{5.75} \times 10^8 = 114 \times 10^8 = 1.14 \times 10^{10}$
(c) $8.5 \times 10^5 - 9.0 \times 10^5 = -0.5 \times 10^{5}= -5 \times 10^4$
(d) $3.6 \times 3.6 \times 10^{2} = 13 \times 10^2 = 1.3 \times 10^3$
