Answer: 8
The radical sign applied to a real number gives the principal square root, which is the positive square root in the case of a positive number.
2 = 2????
Thats what Im getting it from.
Since x is 2 then it would still be 2=2 in simple term.
The answer is -13. You figure it out by multiplying 2.5×-5.2=13
Add like terms
2+4i +7 +11 i =
2+7 + 4i+11i =
9+15i
Step-by-step explanation:
1. k = 76°
2. r = 25cm
3. as the drawing attached
one pair of parallel lines : AB and DC
one pair of equal angles : <em>L</em><em> </em>A and <em>L</em><em> </em>D
4. (7²× 3`¹)⁴×7^5 / (3² × 7^(-6))³
= (7^8 × 3`⁴)×7^5/ (3² × 7^(-6))³
= (7^13 × 3`⁴)/ (3^6 × 7^(-18))
= (7^(31) × 3^(-10))
= 7^31 / 3^10
