\star\:\:\:\bf\large\underline\blue{Question:-}

  • Perform the following calculation and round of the numbers to two digit.

\star\:\:\:\bf\large\underline\blue{Solution:-}

For Question 1.

 \frac{1}{3.4 \times  {10}^{24} }

 = 0.29 \times  {10}^{ - 24}

After rounding, we get,

 = 0.3 \times  {10}^{ - 24}

For Question 2.

 \frac{33}{9.0 \times  {10}^{ - 4} }

 = 3.66 \times  {10}^{4}

After rounding, we get,

 = 3.7 \times  {10}^{4}

For Question 3.

 \frac{1.4 \times  {10}^{9} }{(2.77 \times  {10}^{3})  \times (3.76 \times  {10}^{5} )}

 = 0.14 \times  {10}^{9 - 3 - 5}

 = 0.14 \times  {10}

 = 1.4
