x^2 + 6^2 = 10^2

x^2 + 36 = 100

x^2 = 100-36

x^2 = 64

x = sqrt(64)

x = 8

14. Find the Error Hiroshi is determining -42 – (-37). Find his

vaieri [72.5K]

Answer:

Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.

Step-by-step explanation:

we have

Hiroshi's work

$42-(-37)=42-37=5$

Remember that

a negative number is just a positive number multiplied by -1

and (-1)(-1)=+1

Correct work

$42-(-37)$

$42-(-1)(37)$

$42-(1)(-1)(37)$

$42+(-1)(-1)(37)$

$=42+37=79$

therefore

Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.

Apply the properties of exponents to rewrite each expression in the form kxn, where nn is an integer and x ≠0

professor190 [17]

Answer:

The expression will be $0.333x^{-2}$

Step-by-step explanation:

We have given expression $\frac{x^{-3}x^5}{3x^4}$

We know the property of exponent that when two function are divided then the power of exponent is subtracted and when there is multiplication of two function then exponent is added

So $\frac{x^{-3}x^5}{3x^4}=\frac{x^{2}}{3x^4}=0.333x^{-2}$

So the expression will be $0.333x^{-2}$
