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>

Samuel consumed 2161 calories of food on​ Monday, 2378 calories on​ Tuesday, and 1841 calories on Wednesday. In order for​ Samue
german
Number of calories consumed on Monday = 2161
Number of Calories consumed on Tuesday = 2378
Number of Calories consumed on Wednesday = 1841
Daily average intake is 2200
Let calories intake on Thursday be X

Now ,

Average = sum of total calories/ number of calories

=> 2200 = 2161+2378+1841+X/4

=> 2200 x 4 = 6377 + X

=> 8800 = 6377 + X

=> X = 8800-6377

=> X = 2423

So Samuel must consume 2423 calories on Thursday
