Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25
Answer: The first rule: am × an = am+n. 3. 3. The second rule: (am)n = amn. 3. 4. The third ... three a's at the bottom can be divided out, so we are now left with a4. 1 that is a4. The same answer is obtained by subtracting the indices, that is, 7 − 3=4.
