A^(-b) = 1 / (a^b)

examples : 4^(-3) = 1 / (4^3) = 1 / 64

2 + 4^(-2) = 2 + 1/(4^2) = 2 + 1/16 = 2 1/16

3 * 2^(-2) = 3 * 1 / (2^2) = 3 * 1/4 = 3/4

Subtract (8.4 x 108) − (9.5 x 106).
Step2247 [10]

Based on the fact that the expressions to be subtracted have the same base, the result is 8.305 x 10⁸.

<h3>What is the result of the subtraction?</h3>

The first number in standard form is:

= 8.4 x 10⁸

= 840,000,000

The second number in standard form is:

= 9.5 x 10⁶

= 9,500,000

The result is:

= 840,000,000 - 9,500,000

= 830,500,000

In scientific notation this is:

= 8.305 x 10⁸

The sum of two numbers is 262. The difference of those same two numbers is 172. Which answer choice shows both numbers?
STatiana [176]

Answer:

A = 217

B = 45

Step-by-step explanation:

A+B = 262

A - B = 172

A = 172 + B

172 + B + B = 262

2B = 90

B = 45

A = 172 + (45)

A = 217
