Question

2.9 x 10¹¹ - 3.7 x 10¹³ =

Answer 1

To subtract numbers in scientific notation, we first convert them to have the same exponent, then perform the subtraction. Thus, 2.9 x 10¹¹ - 3.7 x 10¹³ becomes -3.41 x 10¹³.

Step-by-step explanation:

The question asks to subtract two numbers expressed in scientific notation: 2.9 x 10¹¹ and 3.7 x 10¹³.

To perform the subtraction, we need to express both numbers with the same exponent:

• Convert 2.9 x 10¹¹ to 0.29 x 10¹³ by moving the decimal one place to the left and increasing the exponent from 11 to 13.
• Now subtract the two numbers: 0.29 x 10¹³ - 3.7 x 10¹³ = -3.41 x 10¹³.

This is the final result in scientific notation.
