Which expression is equivalent to (3×⁶ + 2׳) - ( ×⁵- 5׳)?

3x^6-x^5+7x^3

Step-by-step explanation:

So we have 3x^6+2x^3, then -x^5+5x^3 (after distributing the negative)

3x^6 cant be added to another number, neither can -x^5 so we can list them as follows

3x^6-x^5

Now 2x^3 and 5x^3 have the same exponent, so you can add them together to get 7x^3

The final solution will be 3x^6-x^5+7x^3 with exponents from highest to lowest.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
