When you multiply exponents, Your add them so you need to add 4 and 2 to get 6. The answer would be C

we have

(5a^{2} b^{3} )(6a^{k}b)=30 a^{6}b^{4}

Multiply the left side and then compare with the right side

(5a^{2} b^{3} )(6a^{k}b)

Combine like terms

(5*6)(a^{2}*a^{k})(b^{3}*b)\\=(30)(a^{k+2})(b^{4})

Compare with the right side

(30)(a^{k+2})(b^{4})=30 a^{6}b^{4}

so

(a^{k+2})=a^{6}

k+2=6

solve for k

k=6-2=4

therefore

<u>the answer is the option C</u>

X is 90 degrees. If AB is the diameter, then it passes through the centre. X is 90 degrees because the angle in a semicircle is always a right angle.

Given F= 9/5C+32, the conversion formula for Fahrenheit to Celsius, solve for C
nata0808 [166]
What do you want to solve for? Substitute in c to find F. To solve for C, 

<span>F - 32 = 9/5(c) </span>

<span>C = 5/9(F - 32)</span>
