Answer:

She can type 180 letters in a minute and a half.

Step-by-step explanation:

6 letters per 3 seconds, so we need to find how many letters per 90 seconds, or minute and a half.

6/3 = x/90

Where x represents how many letters she can type in 90 seconds.

2 = x/90

Multiply by 90.

x = 180.

Julli [10]

Answer:

5

(3a²b³c)³(2a⁴b²c²)³

= (3a⁶b⁹c³)(8a¹²b⁶c⁶)

= 24a¹⁸b¹⁵c⁹

14

⁴√(81a¹⁶b¹²c⁹)

= (⁴√81)(⁴√a¹⁶)(⁴√b¹²)(⁴√c⁹)

= 3 (a^{\frac{16}{4} }) (b^{\frac{12}{4} } ) (c^{\frac{9}{4} } )

= 3a^{4} b^{3} c^{\frac{9}{4} }
