Question

Two math questions I need help with :)

Answer 1

Answer:

1. no

  yes

  yes

2. d¹/³ b is the final answer

Step-by-step explanation:

1. a surd is just an irrational number, so a radical or a never-ending decimal

2.

simplify like we did to the others by distributing the exponent through the parentheses, then combining like terms, and finally combining fractions.

b⁻⁵(cd⁻¹)³   →  b⁻⁵c³d⁻³

d(bc²)⁻¹   →   d b⁻¹c⁻²

d⁻⁵b⁻⁸    →  d⁻²b⁻³    →   d⁻²b⁻³c⁻³

b⁻⁵c³d⁻³         c³

d b⁻¹c⁻²    →  d b⁻⁴c⁻³

  b³c      

divide

d⁻²b⁻³c⁻³    →  d⁻³b

 d b⁻⁴c⁻³

positive indices are just positive exponents; it wants you to make the exponents positive. to do that you find the reciprocal, so you turn the negative exponent into a fraction under the number one and get rid of the negative.

d¹/³b
