Answer:
26 * 26^8 = 26^9
Step-by-step explanation:
Here, we want to write 26 * 26^8 in exponential form.
26* 26^8 is same as 26^1 * 26^8
According to the first law of indices, we are going to add the powers together;
Thus, this gives ; 26^(1 + 8) = 26^9
Answer:30
Step-by-step explanation: Put 30 times 15 into a calulater. Then do 15 times 2 then you find your answer.
Answer:
10
Step-by-step explanation:
The rule of geometric sequence is ⇒⇒⇒ a * r^(n-1)
Where a is the first term and r is the common ratio
for the given sequence √5 , √10 , 2√5 , .......
a = √5
r = √10 / √5 = √2
The ninth term = √5 * (√2)^(9-1) = √5 * (√2)⁸ = 16 √5
the correct answer is the third option 16√5
