Answer:
The correct answer is that s > 4
Step-by-step explanation:
In order to find this, we can stick the -7 in for d and then solve the equation. This will leave us with a value for s.
d + s > -3
-7 + s > -3
s > 4
Answer:
0.00045 
Step-by-step explanation:
450 
⇒
1 = 0.000001
= 450 = 450 × 0.000001 = 0.00045
Answer:
The simplification of the given expression (r3s2t)4 is:
r¹²s⁸t⁴
Step-by-step explanation:
Given expression:
(r³s²t)⁴
power of '4' on the whole term will be applied to individual terms after we open the brackets. In this case the power on the whole term will be multiplied to the power of each individual term:
= (r³)⁴(s²)⁴(t1)⁴
= r³ˣ⁴ s²ˣ⁴ t¹ˣ⁴
= r¹²s⁸t⁴
