Step by step solution

01

Part (a) step 1: Given Information

We need to write180000000 in scientific notation.

02

Part (a) step 2: Calculation

Now,

180000000=1.8×108

So, The scientific notation is1.8×108.

03

Part (b) step 1: Given Information

We need to write 0.00006in scientific notation.

04

Part (b) step 2: Calculation

Now,

0.00006=6.0×10-5

So, The scientific notation is 6.0×10-5.

05

Part (c) step 1: Given Information

We need to write750 in scientific notation.

06

Part (c) step 2: Calculation

Now,

750=7.5×102

So, The scientific notation is7.5×102.

07

Part (d) step 1: Given Information

We need to write 0.15in scientific notation.

08

Part (d) step 2: Calculation

Here,

0.15=1.5×10-1

Therefore, The scientific notation is 1.5×10-1.

09

Part (e) step 1: Given Information

We need to write0.024 in scientific notation.

10

Part (e) step 2: Calculation

Here,

0.024=2.4×10-2

Therefore, The scientific notation is 2.4×10-2.

11

Part (f) step 1: Given Information

We need to write 1500in scientific notation.

12

Part (f) step 2: Calculation

Here,

1500=1.5×103
