Answer:
Step-by-step explanation:
A. 4^5*4^5 = 4^(5+5) = 4^10 ≠ 4^15
B. (5^4)^5 = 5^(4*5) = 5^20
C. 3^1*3^0 = 3^(1+0) = 3^1 ≠ 3^0
D. 6^20/6^10 = 6^(20 - 10) = 6^10 ≠ 6^2
Answer:
C is correct
Step-by-step explanation:
3 groups of -2
Consider the given equation to be f(x) whose first derivative is positive for all real x. This implies f(x) is a strictly increasing function. Thus it has only 1 root.
Answer: <u><em>The first no. is 6 and the second no. is 4.</em></u>
Step-by-step explanation: Let the 2 no. s be x and y respectively.
→x+ 2y = 14
<em>→x-y = 2 </em>
<em>∴ x = 2+y</em>
<em>y = y</em>
∴ x+2y=14
= 2+y+2y=14
3y=14-2
3y=12 , y = 12/3=4
∴y = 4
→x = 2+y
= 2+4=6
∴x=6
<u><em>Thus, the first no. is 6 and the second no. is 4.</em></u>
