Answer
a, $4.22\times10^{3}$
b, $7\times10^{5}$
c, $3.9969$
d, $1.4\times10^{16}$
Work Step by Step
When determining the correct number of significant figures in the result of multiplication and division calculations, The result of a multiplication or division should carry the same number of significant figures as the factor with the least number of significant figures
a, $34.00\times567\div4.564$ = $4.22\times10^{3}$
b, $79.3\div0.004\times35.4$ = $7\times10^{5}$
c, $89.763\div22.4581$ = $3.9969$
d,$(4.32\times10^{12})$ $\div$ $(3.1\times10^{-4})$ = $1.4\times10^{16}$
