(b2) what's the missing exponent<br> = b−10

amid [387]

According to the given expression, the value of b if $b^2=b^{-10}\\$ is -1 and + 1

Indices are expressed using exponents and bases. Some of the useful laws of indices are:

$a^m\times a^n=a^{m+n}\\a^{-n}=\frac{1}{a^n}$

Given the expression;

$b^2=b^{-10}\\$

This can also be expressed as:

$b^2=\frac{1}{b^{10}}\\b^2 \times b^{10} =1\\b^{2+10} =1\\b^{12}=1\\b=\pm\sqrt[12]{1}\\b=\pm1$

Hence the value of b from the given indices is -1 and + 1

Justin invested $7,300 in an account paying an interest rate of 1.5% compounded

lana [24]

Answer: 10.7 years.

Step-by-step explanation:

7,300 * (1 + 0.015)^x = 8,560 <=>

7,300 * 1.015^x = 8,560 <=>

1.015^x = 8,560 / 7,300 <=>

1.015^x = 1.1726 <=>

x = 10.694

To the nearest tenth:

x = 10.7 years
