Question

Perform each of the follow
calculations. Round off your answers
three digits.
a. (3.26 104) (1.54 106)
b. (8.39 107) (4.53 109)
c. 8.94 x 10^6/4.35 x 10^4
d. (9.28 x 10^9) (9.9 x 10^-7)/
(511) (2.98x 10^-6)​

Answer 1

Explanation:

a. (3.26104) (1.54106)

$(3.26104)\times (1.54106)=5.025458302\approx 5.02$

b. (8.39 107) (4.53 109)

$(8.39107)\times (4.53109)=38.02069336\approx 38.0$

c. $(8.94\times 10^6)/(4.35\times 10^4)$

$\frac{8.94\times 10^6}{4.35\times 10^4}=205.5172413\approx 206$

d. $(9.28\times 10^9)\times (9.9\times 10^{-7})/(511)\times (2.98\tmes 10^{-6})​$

$\frac{(9.28\times 10^9)\times (9.9\times 10^{-7})}{(511)\times (2.98\tmes 10^{-6}}=6,033,176.164\approx 6,030,000$

Answer 2

Explanation:-

In this question,

a. (3.26104) (1.54106)

$(3.26104)\times (1.54106)=5.025458302\approx 5.02$

b. (8.39 107) (4.53 109)

$(8.39107)\times (4.53109)=38.02069336\approx 38.0$

c. $\mathbf{\frac{(8.94\times 10^6)}{(4.35\times 10^4)}}$

$\frac{8.94\times 10^6}{4.35\times 10^4}=205.5172413\approx 206$

d. $\mathbf{\frac{(9.28\times 10^{9})\times (9.9\times 10^{-7})}{(511)\times (2.98\times 10^{-6})}}$​

$\frac{(9.28\times 10^9)\times (9.9\times 10^{-7})}{(511)\times (2.98\tmes 10^{-6}}=6,033,176.164\approx 6,030,000$
