Answer:
√7 units, √98 units
Step-by-step explanation:
Pythagorean theorem
a^2+b^2=c^2. So 9+b^2=16. So b^2=7. So b=√7
a^2+b^2=c^2. SO 49+49=c^2. So 98=c^2. So c=√98.
Answer:
1
1
0
0
Step-by-step explanation:
here´s and example for 1
1⁵
1x1x1x1x1=1
so 1 raised to the power of any number is 1
1 multiply by itself any number of times is 1
here´s an example for 0
0⁴
0x0x0x0=0
hence, the vale of 0 raised to any power is 0.
0 multiplied by itself any number of times is 0
Heres a tip---- if it has a square its 90 degrees if it doesnt its 180 and if its in an x shape theyre equal
The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
