Answer:

1.833 x 10^(-5)

Explanation:

When dividing in S.N., divide the coefficients and subtract the exponents

1.67 ÷ 9.11 = 0.183

10^(-7) ÷10^(-3) = 10^(-4)

1.833 x 10^(-5)

\tt(1.67 * 10 ^ { -7 } ) / (9.11 * 10 ^ { -3 } )
To divide exponents with the same base, we must subtract the exponents from the numerator & the denominator.

\tt(1.67)/(9.11* 10^(4))

\tt(1.67)/(9.11* 10000)

\tt(1.67)/(91100)

\boxed{\tt(167)/(9110000)\approx 0.000018332}

So, 0.000018332 = 1.8832×10^(−5)

Hope it helps ⚜
