(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

What are the roots of the equation? x^2 − x − 42 = 0 Enter your answers in the boxes. X= X=

alekssr [168]

Answer:

x = -6 and x = 7

Step-by-step explanation:

x² - x - 42 = 0

find two number which

a + b = -1

a*b = -42

a = -7

b = 6

x² - x - 42 = 0

(x-7)(x+6) = 0

x-7 = 0

x = 7

x +6 = 0

x = -6
